Having played in the group Aleph Null for some years (cdbaby) I can't 
resist jumping into this one:

less serious:
if x > infinity
   throw a_tantrum

more serious:
The new constant of infinity fits nicely into the IEEE FP space, so it 
will function here as aleph one, but I think LiveCode will internally 
cast an integer comparison, so it should also function as aleph null.
